A vhandle (i6-isthreadably attached to the outer threaded end portion of the pistonrodandincludesamen-l larged inner end '66 yfor engagement witha stop whichlimits the outward movement lof the piston rod and length of the strokeof the piston. This handle is adapted to be ad. v justed on the pistonrod to lengthen and shorten its stroke and whereby the amount of lostmotion of the pistonis varied and A spring actuated -pindevice 67is-pro.-

vided in the handle to engage the threaded end portion of thepiston rodfor the purpose' of holding the handle thereon in its adiusted position.This handle also serves to facilider, if desired, and whichremovalisbest ac'- complished by first withdrawing the end of theclosure plug and then shifting the outer end of the rod A37 sidewise,out from the pocket 63.

The cylinder, as before suggested, is pro` vided with a rockermo'tionwhereby its out- Y let is successively brought to register withthe discharge opening 53 of the outer cylinder for the purpose ofreleasing uniform quantities of liquid batter.` In this connection itwill be understood that the piston is operated simultaneously withthisopening rocker movement, -that 1s to sayit 1s shoved Vin at this time ina way to force thebatter out through the lower opening, since Vat thismoment the inlet is closed.

-The purposeof'thisV simple meansof disconnecting the operativeconnectionis to permit, if desired, the machine to--be run empty and`without feedingbatterfto the Vbaking units, which idle operation isobviously .desirable at'times, as forinstancewhen first starting themachineY up and during`the`period ofY heating yup `the baking units.Thebatter feeding device Vherein described,

when applied to a baking machine, would obviously -be connected with theoperating `mechanismV thereof, gand timed'gso 'j that the lbattervfeeding operations wouldbe per-` formed promptly 'with' the positioningof Y the baking irons beneath 'the batter feeding i tate theremoval ofthe rod, piston and cylindevice.Y The several operative features, fof.the feeding device, are connectedfto be operatedfrom the shaft 33 beforementioned and which in turn 4is lconnected to be driven byl a The feedincludes two lines ofoperative connections, one
